RUFF-LING oR PLAlTlNG ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 252,447, dated January 17, 1882.

l Application filed July 2.1881. (ModelJ To all whom it may concern Be it known that I, EDGAR D. FELLows, of Watertown, Jefferson county, New York, have invented a new and useful Improvement in Rut'fling or Plaiting Attachments for Sewing- Maehines, of which the following is a specification.

My invention relates to a sewing-machine attachment; and its main features consist, first, in a guide by which a strip of cloth to be plaited by the rather is carried from side to side across the line of sewing in the arc of a circle whose center is at or near the needle; second, in combinationwiththe guide and ruffler, a camwhicb actuates the guide and gives a peculiar form to thescallops, depending upon the shape of the cam- In the drawings, Figure l is a plan. Fig. 2

. is a. right-hand side elevation. Fig. 3 represents the cam and detached parts. Fig. 4 is a rear elevation. Fig. 5 represents the pawl. Fig. 6 is a section through the cam and ratchet on an enlarged scale. Figs. 7 and 8 represent a modification of the invention,iin which the curve motion is given to the guide by means of a connecting-rod or pitman instead of the cam.

In the general description of my invention,

Figs. 7 and 8 will not be referred to unless specially mentioned in connection with the modification. The'framefof the attachment is fastened by screw b to the base-plate'of a sewing-machine. 'It has a vertical flange, a, which has a horizontal flange, a. Ratchet-wheelo and cams s are on the short shaft or stud e, supported by and turning in the upright flange a of framef. Stud eandthe manner of holdlng cam s bynut w, and ratchet 0 by screw 0 are shown in Fig. 6. Ratchet c is turned by means of lever l and pawl e. The end of lever l is provided with a pivoted book, a, which hooks on the neck of needlenut b. The needle-yoked, needle e needle-bar b and needle-nut b are ordinary. and well-known parts of a sewingqnaehine, The vertical motion of needle-bar Z) in sewing actuates lever l. Pawl e is pivoted to lever l, and is held against the circumference of ratchet-wheel c by spring .9 whose upper end is fastened to the short arm 00 of pawl a, and the lower end needle 6 arms h h are pivoted to frame f in line with the needle, andthe bar It is pivoted to the arms parallel with said line, and extending parallelwith bar 2', pivoted to arm h to the guide m, the distance from arm h to the center of the guide being equal to the distance from needle 0 to where arm h is pivoted to framef. By thus moving guide in in such an are that a straight line lengthwise of the guide and through its center will always 7e strike needlee, all slack in the cloth strip p between the needle and the guide, and also all tendency to twist or wrinkle, so as to impede the work or mar its beauty and regularity, are prevented. V a

Lever g, at its rear end, is pivoted at o to flange a of frame f, and is slotted near its front end, where it is adjustably pivoted to arm W, for the purpose of regulating and determining the extent of movement given to guide m. 8c The same purpose may also be effected by means of slot 2: in flange a. for pivot o to en ter, so that lever g and its fulcrum e will be adjustable to increase or diminish the'distance between fulcrum oand rollers. Barf isbolted to lever g and supports the ends ofshaft 8 on which roller 8 is turned by earn 8. When lever 9 is being adjusted, as above described. roller 8 slides on its shaft 8 Roller s is kept in contact with cam s by the force of spring 0, go which bears against the lateral projection o of arm 71?. Spring 0 is attached to frame f.

Guide on is a thin metallic plate having a slot, n, at its rear end, and also provided with a a tension-spring, m, having one or more slots, 5 m near its front end, for strips of cloth of different widthsto pass through.

The rattling-blade n and a section of the arm n (shown in Fig. 1) are parts of the ruffler.

jointed to lever I, prevents lateral strain on the needle-bar and allows the hook to accommodate itself to the neck of the needle-nut b. v

The pawl e, by being recessed or slotted, as shown in Fig. 5, to receive the ratchetteeth, leaves a support on the pawl at each side of the teeth to sustain the direct strain of turning the ratchetwheel 0, and also prevents thepawl from being pulled away from the ratchet by any lateral motion given to it by needle 6 when taking along stitch. Spring 8 by being attached to the base of frame f and to the short arm .00 of pawl e, not only keeps the latter in contact with the ratchet, but also prevents hook c from becoming dislodged from the neckof the needle-nut. ratchet-teeth are in such relative positions that the ratchet e and guide m, with intermediate parts, are moved by the pulling force of the pawl.

By taking oif srrew-uut w the cam 8 may be removed and a different-shaped cam put in its place for thepurpose of changing the form of the scallops in the plaiting. The cam may be of a form that will produce the same shaped scallops that would be made by using instead of the cam a connecting-rod or pitman, a, as

\ s hown in Figs. 7 and .8, to connect an extension, 00, on either of the arms h h with the ratchet-wheel c, and if such a shaped scallop be desired the cam might be removed, and one of the arms h h or lever g be actuated by a ratchet-wheel through a pitman. In the modification as shown in Fig. 8, spring to on stud 00 produces the necessary tension on ratchet c to 1 prevent its being turned by the pawl sliding over the ratchet-teeth.

- In my invention as I have described it the guide in every position points directly toward the needle; but it may be ofapproximate though less value if the guide moves in the arc, as described, without the center line lengthwise of the guide always pointing to the needle, as would be the result if the bard were dispensed with and the guide rigidly attached to the projecting end of bar h. The guide may 7 also be movedin an are by dispensing with all the bars, arms, and levers except lever l and arm h and connecting the latter by a pitman with the ratchet, or a wheel rotated by a friction-clutch as a substitute or equivalent for a ratchet the guide being rigidly attached to arm h. In all such modifications the guide will move in an arc whose radius will be either directly or approximately in line with the needle.

'I do not claim as a part of this invention Pawl e and the the combination of the ruffler witha reciprocating strip-guide, both in one attachment, nor the combination of the ruffler with a stripguide having a pendulous motion, such claims having already bcen made by me in another application for Letters Patent for an improvement in plaiting attachments for sewing-machine's, filed June 27, 1881.

I claim as my invention- 1. A cloth-guide having reciprocating motion across the line of sewing in an arc of a circle whose radius is in line, or approximately in line, with the needle, in combination with the ruffler, said guide being adapted to be connected with and operated by sewing-machine mechanism, for the purpose of forming scalloped plaitin g, substantially as described.

2, A cloth-guidehaving reciprocating motion across the line of sewing and adapted to machine mechanism, in combination with the rufiler and with acam to determine the shape of the scallops, for the purpose of forming scalloped plaiting, substantially as described.

3. The ratchet-wheel c and its pawl and cam s, or their equivalent, in combination with guide m and levers and. bars arranged intermediate the guide and ratchet, to transmit to the guide a reciprocating motion in an arc of a circle whose center is at the needle of the sewing-machine, substantially as described.

4. The springshaving one end attached to pawl e and the other and lower end to frame f, in combination, with pawl e, ratchet c, lever l, and book 0, said book being adapted to engage the needle-nut b, substantially as described.

5. The parallel arms h h pivoted to frame f in line with needle 6 in combination with guide m and the bar 11, pivoted to said arms and parallel with said line, substantially as described.

6. The parallel arms h M, pivoted to frame f in line with needle 6, in combination with guide at and bars h and t, the bars h and 6-being parallel with each other and with said line and pivoted to the guide and to arm h, and bar. h being also pivoted to arm h substantially as described.

7. The slotted adjustable lever g and frame f, slotted at 2: in combination with cam s and the pivoted arm h substantially as described.

8. The adjustable lever g, provided with sliding roller 8 and its shaft 8 in combination with cam s and pivoted arm k and framef, substantially as described.

9. The lever I; provided with hook a, pawl.
